[A case of R0 resection in conversion surgery after duodenal stent placement for locally advanced unresectable pancreatic cancer with duodenal stenosis].

A 67-year-old man presented to our hospital with vomiting. Esophagogastroduodenoscopy revealed duodenal stenosis and atypical epithelium. A tumor in the pancreatic head, about 30mm in size, involving the superior mesenteric artery and a superior mesenteric vein was identified using abdominal contrast computed tomography (CT).

[Bleeding due to acquired hemophilia A in acute pancreatitis: a case report].

Acquired hemophilia A leads to severe bleeding and is known to be related to many underlying diseases; however, it has not been reported to occur as a complication of pancreatitis. We present a case of acquired hemophilia A secondary to severe acute pancreatitis. A 76-year-old female developed a hematoma in the lower leg muscle while being treated for severe acute pancreatitis.

Effectiveness and clinical results of endoscopic management of sigmoid volvulus using unsedated water-immersion colonoscopy.

Background And Aim: Although intestinal obstruction as a result of sigmoid volvulus (SV) may be successfully resolved using endoscopic detorsion, surgical treatment remains the main therapeutic strategy. We evaluated the endoscopic detorsion procedure using unsedated water-immersion colonoscopy for the treatment of SV.

Methods: A retrospective chart review was conducted on the clinical background and prognosis of 21 SV patients who underwent 71 endoscopic detorsion procedures using unsedated, water-immersion colonoscopy.

Early-onset diffuse gastric cancer associated with a de novo large genomic deletion of CDH1 gene.

A 41-year-old man with no familial history of gastric cancer was diagnosed as with intramucosal early gastric cancer. Two months after the first endoscopic submucosal dissection for signet-ring cell carcinoma (SRCC), the appearance of previously unrecognized multiple erosions of SRCC was noticed. Pathological examination after a total gastrectomy and Roux-en-Y reconstruction with D2 lymph node dissection were performed.

A case of acute hepatitis B related to previous gynecological surgery in Japan.

A 41-year-old woman became ill with acute hepatitis B after gynecological surgery performed by a surgeon who was hepatitis B surface antigen positive. The surgeon was positive for hepatitis B e antigen, and HBV DNA concentrations in the serum, saliva, and sweat of the surgeon were very high. HBV genotype and partial HBV DNA sequences from the HBV-infected surgeon were identical to those in the HBV-infected patient.

Spontaneous regression of hepatocellular carcinoma repeated 3 times with invasion of portal vein and inferior vena cava: report on a rare case.

A 65-year-old man suffered from advanced hepatocellular carcinoma in the right lobe of the liver, for which he received no treatment. His serum was positive for hepatitis C antibody. In spite of his poor prognosis, he remained in good clinical condition and at 6-month follow-up the tumor had regressed without specific treatment, as assessed both radiologically and from a decrease of a previously elevated serum tumor marker level (1st regression).
